Amauromine is a neutral antagonist of the cannabinoid (CB) receptor CB1 that is selective for CB1 (Ki = 178 nM; Kb = 66.6 nM) over CB2, with no activity at CB2 receptors at concentrations up to 10 µM. It is also an antagonist of GPR18 (IC50 = 3.74 µM). Amauromine has vasodilatory activity.

GPR18 Inhibiting Amauromine and the Novel Triterpene Glycoside Auxarthonoside from the Sponge-Derived Fungus Auxarthron reticulatum
Planta Med 2015 Aug;81(12-13):1141-5.PMID:26287693DOI:10.1055/s-0035-1545979.
The marine sponge-derived fungus Auxarthron reticulatum produces the cannabinoid receptor antagonist Amauromine (1). Recultivation of the fungus to obtain further amounts for more detailed pharmacological evaluation of 1 additionally yielded the novel triterpene glycoside auxarthonoside (2), bearing, in nature, a rather rare sugar moiety, i.e., N-acetyl-6-methoxy-glucosamine. Amauromine (1), which inhibited cannabinoid CB1 receptors (Ki 0.178 µM) also showed antagonistic activity at the cannabinoid-like orphan receptor GPR18 (IC50 3.74 µM). The diketopiperazine 1 may thus serve as a lead structure for the development of more potent and selective GPR18 antagonists, which are required to study the orphan receptor's potential as a new drug target. Despite the execution of many biological assays, to date, no bioactivity could be found for auxarthonoside (2).
Amauromine, a new vasodilator. Taxonomy, isolation and characterization
J Antibiot (Tokyo) 1984 Nov;37(11):1320-23.PMID:6511659DOI:10.7164/antibiotics.37.1320.
Amauromine is a new alkaloid with vasodilating activity obtained from the culture broth of Amauroascus sp. No. 6237. Its molecular formula was determined to be C32H36N4O2 on the basis of elementary analysis and high resolution mass spectroscopic measurement. It has low toxicity in mice.
AgNTf2-Mediated Allylation with Allylsilanes at C3a-Position of Hexahydropyrroloindoles: Application to Total Syntheses of Amauromine Alkaloids
Org Lett 2017 Oct 6;19(19):5308-5311.PMID:28926277DOI:10.1021/acs.orglett.7b02602.
A protocol for the allylation at the C3a-position of hexahydropyrroloindole using allylsilanes is developed. AgNTf2 proved to be an efficient activator of halopyrroloindoline substrates. This method is applicable to the introduction of various allyl groups including the reverse prenyl group. The utility of this reaction is demonstrated by total synthesis of Amauromine alkaloids. Stepwise bromocyclizations of the bis-indolylmethyl diketopiperazine derivative and subsequent double reverse prenylation furnished (+)-novoamauromine and (-)-epiamauromine.
Diastereodivergent Reverse Prenylation of Indole and Tryptophan Derivatives: Total Synthesis of Amauromine, Novoamauromine, and epi-Amauromine
Angew Chem Int Ed Engl 2016 Apr 4;55(15):4798-802.PMID:26969898DOI:10.1002/anie.201509468.
A regio- and stereoselective reverse prenylation of indole and tryptophan derivatives is presented. All four possible stereoisomers are accessible through this iridium-catalyzed reaction. The stereoselectivity is controlled by a chiral phosphoramidite ligand in combination with an achiral borane additive and can be switched by changing the nature of the borane. One enantiomer of the ligand is thus sufficient to prepare all possible isomers. The synthetic potential of this method was demonstrated by a short total synthesis of Amauromine and its two natural diastereomers.
α-Glucosidase Inhibitors from the Fungus Aspergillus terreus 3.05358
Chem Biodivers 2015 Nov;12(11):1718-24.PMID:26567949DOI:10.1002/cbdv.201500027.
One new diketopiperazine alkaloid Amauromine B (1), along with three known meroterpenoids, austalide B (2), austalides N and O (3 and 4), and two known steroids (5 and 6), was isolated and identified from the culture broth of the fungus Aspergillus terreus 3.05358. Their structures were elucidated by extensive spectroscopic techniques, including 2D-NMR and MS analysis, the absolute configuration of 1 was unambiguously established by single crystal X-ray diffraction analysis. All the isolates were evaluated for their inhibitory effects on α-glucosidase. Amauromine B (1) and austalide N (3) exhibited more potent α-glucosidase inhibitory activities than the positive control acarbose.
